Determination of Air Leakage of Auxiliary Ventilation Ducting Sys- tem in VANG DANH Underground Mine

Phuongthao Dang, Vanduyen Bui


Air leakage of air movement through the ducting system in underground mine is an important factor in ensuring the
efficiency of ventilation during mining roadways being driven in mine. This value plays an important role in the reasonable design
of auxiliary ventilation as well as in the energy cost in the mine.
Experimental data of the duct air leakage are made on 0.8 m diameter ducts over sections of ducts installing towards the working
face in Vang Danh mine. Determination of the air leakage in ducting system have been undertaken.
